|---|---|
void |
close()
Close the iterator.

Item |
current()
Get the current item in the sequence.
|
UnfailingIterator |
getAnother()
Get another iterator over the same sequence of items, positioned at the
start of the sequence.

UnfailingIterator |
getReverseIterator()
Get a new SequenceIterator that returns the same items in reverse order.
|
boolean |
hasNext()
Determine whether there are more items to come.
|

SequenceIterator(Currently, closing an iterator is important only when the data is being "pushed" in another thread. Closing the iterator terminates that thread and means that it needs to do no additional work. Indeed, failing to close the iterator may cause the push thread to hang waiting for the buffer to be emptied.)

and SequenceIterator.LOOKAHEAD. It is always
acceptable to return the value zero, indicating that there are no known special properties.
It is acceptable for the properties of the iterator to change depending on its state.Copyright (c) 2004-2013 Saxonica Limited. All rights reserved.
